The same team that created a camera with light-speed shutter rates has now expanded upon their project, with a camera capable of seeing around corners. Literally. To do this, the system uses a so-called femtosecond laser to send out extremely short light pulses -- so short, in fact, that their entire lifespan is measured in quadrillionths of a second. To capture an object lurking around a corner, the device aims its laser at a nearby wall, thereby allowing the light to bounce around the room before eventually landing on the concealed object. Once it hits the jackpot, the light will reflect back onto the wall, and eventually return to a detector, which can gauge the exact location of the object based on the distance the laser traveled. This happens over and over again at different angles, meaning that the system will ultimately be able to get a general idea of the hidden room's layout. Researchers hope that their system will eventually be used in emergency rescue situations, or to help drivers see what's around the bend, though there's no telling when any of that could actually happen.

I doubt something like this will be available to the average consumer. It will take about 10 to 20 years before someone even thinks about bringing this to market. The only customer today is the Military.
